Leveraging cloud-based supercomputing to accelerate climate solutions
Scientists say the global climate crisis is continuing to intensify, and managing the situation requires increasingly innovative solutions.
A central part of this work is the simulation of Earth's climate over time in probable scenarios for climate change, and of the climate with different scenarios for intervention."We use large earth system models to perform these simulations together with high resolution models of key parts of the system like the stratosphere," says Lamarque, who says that these models are some of the largest high-performance computing workloads in existence.
"While carbon dioxide emissions are going down, it's not currently as fast as we understand we need for a safe climate," Lamarque warns."It's pretty much a given now that we will exceed 1.5°C as a global average measure in the next decade or two, which official bodies describe as a key threshold for more severe climate impacts." Notably, Earth's average temperature has already temporarily crossed this critical threshold.
"High-performance computing is indispensable for our climate research," Lamarque explains."We've conducted large-scale simulations on these systems, utilizing millions of core hours to run full-fledged climate models effectively. This shift to cloud-based HPC allows us to perform extensive simulations that were previously only possible on traditional supercomputers, paving the way for accelerating innovative climate solutions.
